The Nobel Gases Flashcards
(6 cards)
1
Q
Why are the elements of Group 0 unreactive?
A
Because their atoms have a stable arrangement of electrons
A full outer shell
2
Q
Describe the trend going down group 0
A
The boiling points of elements increases going down the group.
Densities increase going down the group
3
Q
Why can the Nobel gases be used in light bulbs?
A
Because they will not react with the hot metal filament
4
Q
Why do the Nobel Gases remain monatomic?
A
They are unreactive and exist as single atoms instead of forming molecules because their electron configuration is already stable.
5
Q
Why do the boiling point of the Nobel Gases increase going down the group?
A
Because their relative atomic mass increases going down the group
6
Q
Why are the Nobel Gases useful as balloons?
A
They have low densities
